A restful night's sleep may help us stay on good terms with our colleagues, however.
Scientists from West Texas A&M University analysed 131 employees over two weeks. Perhaps unsurprisingly, insomnia was linked to fatigue the next day, which then triggered so-called "cyber incivility".

Unwinding with a relaxing book, warm bath or soothing music at the end of a stressful day may therefore keep things harmonious from 9 to 5.
Insomnia is thought to affect up to a third of British adults to some extent.
Over time, a lack of sleep has been linked to heart disease, cancer and even an early death. In the short-term, many feel irritable the next day.
To better understand how this poor mood affects our performance at work, the West Texas scientists had 131 full-time employees keep two daily diaries for a fortnight.
At 7am every day, the participants noted how they slept the night before.
Come 4pm, they recorded any fatigue or cyber incivility – "rudeness or impoliteness enabled by technology". This may have included ignoring a request to schedule a meeting or making "demeaning or derogatory remarks through email".
Results – published in the journal Sleep Health – suggest "employees have more self-regulatory fatigue and thus engage in higher levels of cyber incivility at work after a shorter night of sleep".
Being "agreeable" lessened this effect, however.
"Our findings build on previous research that suggests self-control is restored while people sleep, to the extent that after a poor night’s sleep, people lose their self-restraint and are more likely to engage in cyber incivility at work the next day", said lead author Dr Trevor Watkins.
Tips for a good night's sleep
People who struggle to sleep are advised to go to bed and wake up at the same time every day, even on weekends.
Winding down with gentle yoga or other relaxing activities can also help. Writing a to-do list for the next day may also calm a frazzled mind.
In addition, experts recommend people avoid screens – like their phone – for around an hour before bed.
Bedrooms should be "sleep friendly", with a comfortable mattress, pleasant temperature and black-out curtains, if necessary.
Keeping a sleep diary can help people link a poor night's shut eye to lifestyle habits, like drinking too much coffee or alcohol.
